Product description

Allium Rosy Dream brings a soft, romantic touch to the garden with its perfectly rounded, rose pink flower heads held on slender stems above fresh green foliage. This graceful Ornamental Onion adds gentle height and structure without overwhelming the border, blending beautifully with perennials, grasses, and other early season favourites. Its pastel tones create a light, airy feel, making it an ideal choice for adding subtle colour and movement to mixed plantings.

These bulbs are easy to grow and thrive in well drained soil and a sunny position. Plant them in autumn, placing each bulb at a depth around three times its height, and space them approximately 15-20cm apart so they have room to develop strong stems and full flower heads. Once established, they need very little attention, returning reliably each spring with their soft, cloud like blooms. Allow the foliage to die back naturally after flowering so the bulbs can store energy for the following year, ensuring a dependable, elegant display season after season.

These bulbs are supplied at a size of 6+.

Instructions

Top Tip

Leave Allium seed heads standing once the blooms fade - they dry into beautiful sculptural forms that add interest well into autumn.

How to Water

Water Allium bulbs sparingly after planting to help them settle into the soil, then leave them to establish naturally over winter. In spring, give them an occasional drink during long dry spells to support strong stem and flower development.

How to Plant

Plant Allium bulbs in autumn in well‑drained soil, setting each one at a depth roughly three times its own height with the pointed tip facing upwards. Space them about 15–-20cm apart so each bulb has room to develop tall, upright stems without crowding.
